How the Eye Becomes Perfected.

Science gives us interesting details about what the human eye has been and trbat it may. become. The Vedas of India, which are the most ancient written documents, attest that in times the most remote, but still recorded in history, only two colors were known, black and red. A ‘vtry long-time elapsed before the eye arrived at the ’perception of the color yellow, and a still longer time before green was distinguished; and It is remarkable .that ip the most ancient languages the terms which designated yellow insensibly passed to the signification of green. The Greeks had, according to the received opinion now, the perception of colors very well developed; and yet authors of a more recent date assure us that in the time »f Alexander, Greek painters had for fundamental colors only white, biaqk, red and yellow. The words to designate blue and violet Were wanting “to the Greeks in the most aaclent times of their histoiy; they called these colors grey and'black. It is thus that the colors of I the. rainbow were oply distinguished .gradually, and the great Aristotle only knew fourof them.''fit is 'a well-ktiown fact that when the colors of the prism are photographed there remains outside the limit of the blue and violet in the spectrum a fiistipst impression, which our do. not reboghize as a'color. Accordinte to physiologists, a time Will'come when the! human eye will be perfected so as to discern tjiis color as well as the others.—Jreu/cif Press and Circular.
